Hi @IT_KA-Sulingen 

Thanks for reaching out to TP-Link Business Forums.

You can refer to this How to Configure VoIP on Omada Router - Business Community

If you fail to configure VoIP feature, please let us know the error message.

Hope it may help.

Thank you for your reply. But we are working with the omada controller.

At the Stand Alone mode it works fine, but not with Omada controlled mode.

Hi @IT_KA-Sulingen 

If you manage the gateway in Controller mode, you can refer to the User Guide - Chapter 5.8 Configure VoIP Settings on Page 118-130: Omada SDN Controller_V6.2_User Guide | Omada Network Support

Thank you for your advice. I can read and understand the manual, but the error is not in front of the PC, but is Omada itself.

Hi @IT_KA-Sulingen 

Could you please upload some screenshot of your settings and the error messages so we can know it better?
